'ALONZO HARRIS, or ATroomr-rlmriors, ASSIGNOR .OF ONE-HALF TO i oTro'scHLLiNc, or 'MATTOON, ILLINOIS.

I JOURNAL-BOX H OlST.

'- Tow/ll whom it may concern:

zen of the United States, residing at Mat- I toon,; county of ,Coles,and State of Illinois,

5 have invented certain new and useful .Im-

provements in J ournal-Box Hoists, of which the following is aspecification.

. The object of this invention is to provide means for lifting acar-truck frame without the necessity for applying jacks orliftingscrews, which device is applicable to all styles of trucks andmay be readily set up in position foruse and which will be strong,durable, and easily applied and operated.

Another object of the invention is to obviate the possibility of injuryto the truck mechanism by carelessness in the use of the device, and thefinal object is to simplify the construction-and arrangement of theparts andincrease the efficiency of the device correspondingly.

The invention consists in the features of construction and combinationof parts hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of the device, showing themethod of using the same;.Fig 2, a cross-sectional elevation showing thehoist in proximity tothe rail, and Fig. 3a top or plan view of the skidwith the shoe mounted thereon.

The hoist consists, essentially, of two parts' an incline or skid 1 anda slidable shoe 2. The incline or skid is preferably of I formation,having upper flanges 3 and lower flanges 4, and an intermediate web 5.Formed on the under face of the lower flanges are arranged a pluralityof teeth or pins 6, which are suitably spaced to be inserted into adjac'ent ties. As shown, the skid or incline is of sufficient length tobridge the distance between three ties, although the device may 4 belonger or shorter, as desired, and the forward upper end 7 of the skidor incline is rounded to permit the shoe to slide over the end of theskid or incline without difficulty. The upper face of the incline isprovided in its center with a V-shaped groove 8, extendinguninterruptedlyfrom end to end of the skid or incline and being cut inthe forward or 5 rounded end of the incline for a considerable distance.The groove is adapted to receive a Specification of Letters Patent.

\ /shaped rib 9 on the under face of the shoe, and the shoe is providedat its forward end with a stop or abutment 10.

In use the device is positionedadjacent to and outside of a rail byinserting the teeth or pins into the top surface of the adjacentties,after which the truck-frame to be raised is brought into position forthe journal-box to rest upon the top face of the shoe and abut againstthe end stop, after which the truck is carried or drawn forward, whichcompels the forward travel ofthe shoe along the incline by reason of thecontact of the stop or abutment against the journal-box, and this travelof the shoe raises the shoe and the truckframe supported thereby. Thegroove 9 extends from end to end of the incline or skid, and the forwardor u per end of the groove is unobstructed, so that the shoe will slideover the end of the skid or incline in case the truck is drawn forwardtoo far, which permits the parts to drop into place without injury, andthe curvature of the forward end of the skid permits this sliding overor tilting of the shoe in an easy and gradual manner, which .obviatesall danger of breakage or injury. If the forward end of the slot'orgroove were obstructed or terminated back of the end of the skid orincline, an excess movement of the truck would tend to tilt up the rearend of the skid or incline by reason of continued pressure against theforward end, and this tilting might have the effect of derailing thetruck or causing serious injury. By allowing the shoe to slide over inthe manner indicated the danger of such derailing or injury is obviatedand the value and efiiciency of the device thereby increased.

by Letters Patent, is- 1 ,1

1. A journal-box hoist comprising an incline or skid having in its upperface an uninterrupted longitudinally-extending groove open at theforward end, and a shoe provided with a rib adapted to travel in thegroove, substantially as described.

2.. A journal-box hoist comprising an incline or skid having in itsupper face an uninterrupted longitudinally-extending groove open at theforward end, ashoe provided with a rib adapted to travel in the groove,

v to travel 1n the groove, substantially as deand having a sto orabutment adapted to I to travel in th position a journa -boX,substantially as described.

3. A journal-box hoist comprising an in cline or skid having a roundedforward upper corner and having in its upper face alongit1idinallyextending uninterrupted groove or channel conforming at its forward endto the curvature of the upper corner, in combinationwith a shoe providedwith a rib adapted scribed.

-' 4. A journal-box hoist comprising an in- I cline or skid having arounded forward upper corner and having 1n its upper facea'longitudinallyextending uninterrupted groove or channel conforming atits forward end to the curvature of the upper corner, in combinationwith a shoe provided with a rib adapted ward end a stop or abutment ada)ted to position a journal-box, substantia ly as described.

5. A journal-box hoist comprising an ine groove and having in its for-2c cline or skid and a shoe adapted to travel on 25 .the upper face ofthe skid, one of the members being provided with a rib and the otherwith a groove, the rib and groove adapted to ALONZO HARRIS.
